Linux解决Device eth0 does not seem to be present

 　　CentOS Linux解决Device eth0 does not seem to be present

　　在VMware里克隆出来的CentOS Linux。。

　　ifconfig...没有看到eth0.。然后重启网卡又报下面错误。

　　故障现象：

　　解决办法：

　　首先，打开/etc/udev/rules.d/70-persistent-net.rules内容如下面例子所示：

　　# vi /etc/udev/rules.d/70-persistent-net.rules

　　# This file was automatically generated by the /lib/udev/write_net_rules

　　# program, run by the persistent-net-generator.rules rules file.

　　#

　　# You can modify it, as long as you keep each rule on a single

　　# line, and change only the value of the NAME= key.

　　# PCI device 0x1022:0x2000 (pcnet32)

　　SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:8f:89:9

　　7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth0"

　　# PCI device 0x1022:0x2000 (pcnet32)

　　SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*", ATTR{address}=="00:0c:29:50:bd:1

　　7", ATTR{type}=="1", KERNEL=="eth*", NAME="eth1"

　　记录下，eth1网卡的mac地址00:0c:29:50:bd:17

　　接下来，打开/etc/sysconfig/network-scripts/ifcfg-eth0

　　# vi /etc/sysconfig/network-scripts/ifcfg-eth0

　　将 DEVICE="eth0" 改成 DEVICE="eth1" ,

　　将 HWADDR="00:0c:29:8f:89:97" 改成上面的mac地址 HWADDR="00:0c:29:50:bd:17"

　　最后，重启网络

　　# service network restart

　　或者

　　# /etc/init.d/network restart

　　正常了。
